Limits of interpretation
The INCI list shows which ingredients are present, not how much of each. Above 1%, ingredients are listed in descending order of weight; below 1% the order is free.
The number 10 refers to the average degree of ethoxylation, so the raw material is a mixture of molecules.
Functions
- Skin conditioning – emollient
- Acting as lubricants on the skin surface providing the skin with a soft and smooth appearance.
- Surfactant – emulsifying
- Helping suspensions or dispersions of liquids in a second liquid by reducing the surface tension of the substances to be emulsified.
